Overview
Color correction refers to various adjustments to the color video signal
(including black/white level, gamma, and knee values). With the DVS-7250
system, you can carry out the following operations.
• Input video processing
• Primary color correction
• Secondary color correction
• RGB clip
• Output video processing
• Luminance processing

To carry out color correction, the BKDS-7420 Color Correction Board is
required. It provides color correction for two channels.
Selecting signals for color correction and color-corrected
signals
To select signals for color correction
To carry out color correction on a signal on channel 1 or channel 2, assign the
signal to the frame memory 1 (FRAME MEM 1) or frame memory 2
(FRAME MEM 2) bus, correspondingly.
To select color-corrected signals
To use the channel 1 or channel 2 signal to which color correction has been
applied, select the frame memory 1 or frame memory 2 output using the
corresponding cross-point button on the required cross-point button row.
Note
When chroma key is selected as the key type for an M/E keyer, you cannot
select a frame memory output signal on the cross-point button row for the M/
E keyer. Conversely, when a frame memory output signal is selected on the
cross-point button row for an M/E keyer, you cannot select chroma key as the
key type for the M/E keyer.
